The REPCO Oil Seal 1.500x2.750x0.375 LGS NBR is designed for industrial rotary shaft applications requiring lubricant retention around a 1.500-inch shaft within a 2.750-inch housing bore.

Installed between the rotating shaft and stationary housing, the sealing element maintains controlled radial contact with the shaft surface to help reduce leakage of compatible oil or grease while supporting protection of bearings, gears, pumps, motors, transmissions, and other internal rotating components.

The product is identified by the REPCO manufacturer designation LGS. This is a manufacturer-specific profile code. The exact sealing-lip geometry, number of lips, dust-exclusion arrangement, outside-case construction, internal reinforcement, spring configuration, lip orientation, and installation direction should be verified against the original REPCO seal, technical drawing, or equipment specification before replacement.

Manufactured from NBR (Nitrile Butadiene Rubber), the sealing element is generally suitable for:

• Mineral oils
• Gear oils
• Hydraulic oils
• Bearing grease
• Petroleum-based lubricants
• General industrial lubricating fluids

NBR generally provides good resistance to petroleum-based oils, grease, abrasion, and mechanical wear under normal industrial conditions. Compatibility should be verified before use with aggressive chemicals, certain fuels, specialized synthetic lubricants, ozone-rich environments, or continuous elevated-temperature service.

The inch dimensions convert approximately to:

Shaft diameter: 1.500 inches or 38.10 mm

Housing diameter: 2.750 inches or 69.85 mm

Seal width: 0.375 inch or approximately 9.53 mm

The 1.500 × 2.750 × 0.375-inch configuration is suitable for compact-to-medium bearing housings, industrial gearboxes, pumps, motors, mechanical drives, and machinery using an inch-size rotary shaft-sealing arrangement.

📊 Specifications

Brand: REPCO

Model / Profile: LGS

Size: 1.500 × 2.750 × 0.375 inch

Metric Equivalent: Approximately 38.10 × 69.85 × 9.53 mm

Type: Industrial Rotary Shaft Oil Seal

Material: NBR (Nitrile Butadiene Rubber)

Profile: LGS

Construction: Manufacturer-Specific REPCO LGS Rotary Shaft-Seal Construction

Lip Design: LGS profile; verify exact sealing-lip geometry, number of lips, and orientation against the original seal or technical drawing

Dust Lip: Verify from the actual LGS cross-section

Spring Type: Verify from the actual LGS seal construction

Shaft Diameter (ID): 1.500 inches / 38.10 mm

Housing Diameter (OD): 2.750 inches / 69.85 mm

Width: 0.375 inch / approximately 9.53 mm

Pressure Capability: Low-pressure rotary shaft-sealing service unless otherwise specified

Lubrication: Compatible oil and grease

Temperature Range: Typically approximately -30°C to +100°C for standard NBR; verify actual compound, lubricant, shaft speed, and operating conditions

Speed Consideration: Permissible speed depends on shaft diameter, shaft finish, lubrication, temperature, alignment, concentricity, runout, lip loading, and actual NBR compound

Installation Consideration: Confirm shaft finish, shaft hardness, housing-bore condition, installation depth, lip orientation, concentricity, runout, and protection from sharp shaft edges before fitting

Application Class: Compact-to-Medium Industrial Bearing and Rotating Equipment

Standard: Inch-Size Specialized Industrial Seal

🔁 Equivalent

Suitable replacement or cross-reference candidate for compatible:

• REPCO LGS NBR Rotary Shaft Seal
• REPCO 1.500x2.750x0.375 Oil Seal
• 38.10x69.85x9.53 Rotary Seal
• 1.500-Inch Shaft Oil Seal
• Inch-Size NBR Rotary Shaft Seal
• Industrial Bearing Housing Seal
• Industrial Gearbox Shaft Seal
• Industrial Pump Shaft Seal
• OEM LGS Profile Oil Seal
• Industrial NBR Shaft Seal

The same dimensions alone do not guarantee interchangeability. The replacement must match the original LGS cross-section, sealing-lip geometry, lip orientation, outside-case construction, reinforcement arrangement, spring configuration, installation direction, material compound, and operating requirements.

(Always verify dimensions, LGS-profile geometry, lip direction, shaft finish, shaft hardness, housing condition, installation depth, lubricant compatibility, rotational speed, temperature, concentricity, runout, pressure, and operating conditions before ordering.)
